IMPROVEMENT IN CALKS FOR'HORSESHOES.

Specification forming part of Letters Patent No. 135,081, dated January21, 1873.

To all whom it may concern:

Be it known that I, THOMAS M. CLARKE, of Winsted, in the county ofLitchfield and State of Connecticut, have invented a new Improvement inToe-Calks for Horseshoes; and I do hereby declare the following, whentaken in connection with the accompanying drawing and the letters ofreference marked thereon, to be a full, clear, and exact description ofthe same, and which said drawing constitutes part of this specification,and represents, in

Figure 1, a perspective view; Fig. 2, a transverse central section; andin Fig. 3, a transverse central section with the pin inserted.

This invention relates to an improvement in that class of toe-calks forhorseshoes which are made with one or more tenons or projections upontheir upper edge, by means of which they may be temporarily attached tothe shoe preparatory to welding.

Heretofore these have been made by cutting the metal away to leavetenons or projections, or in dies to forge the projections; butinvariably require some such mechanical operation and considerable wasteof material.

The object of this invention is to save the metal and avoid the labor,thereby producing a cheaper article; and it consists in constructing thecall; with one or more perforations vertically, or nearly so, throughit, and through which, when placed upon the shoe, a pin may be driveninto the shoe to secure the two together.

A is the calk, cut from bars of metal rolled into the required form intransverse section,

and each calk perforated vertically, or nearly so, with one or moreperforations, a, as seen in Figs. 1 and 2. By preference, in preparingthese for the consumer, I insert a pin, d,,from the outer edge, as seenin Fig. 3, extending nearly or quite through the perforation, and makethis pin tapering at the point. The consumer, after having heated theshoe, places the calk thereon in the required position, then drives thepin or pins through into the shoe, which temporarily attaches the calkto the shoe in its required position that the two may be heated togetherand welded in the usual manner.

The advantage of this construction over that of the projecting studsbefore referred to is that the surface of the calk which rests upon theshoe is perfectly flat, and will lie upon the shoe without holding, thisnecessary holding of the calk being an inconvenience in the attachmentof the calk to the shoe.

The call: is complete as an article of manufacture without the pins, asthe consumer may furnish these himself.

Another advantage is that the calks may be cut from a bar of ironwithout waste, and perforated at a trifling cost, very much less thancalks having tenons or studs formed thereon.

I do not claim a toe-calk having projecting studs or tenons upon theupper ed go.

I claim as my invention As an article of manufacture, thehereindescribed toe-calk, having one or more perforations vertically, ornearly so, therethrough, substantially as set forth.
